Abstract

The increases service life of gas hot water supply boilers with uniform heat supply along of the depth (width) of the combustion chamber for more than 40 years, by using of slot bottom burners was shown. While reducing nitrogen oxide emissions by using of dual-screens its can significantly increase the heat stress of the furnace, the volume of the furnace chamber and the temperature of the flue gases had left unchanged. The boilers with a capacity of 1–10 MW, with the above technical design solutions of the Gas Institute of the NAS of Ukraine, with a total heat capacity of more than 60 GW, continue to be operated and produce in Ukraine and the CIS countries. Installed boilers relatively nitrogen oxide emissions comply with new EU directive (EU) 2015/2193. The using of gas slot bottom burners can reduce nitrogen oxide emissions by approximately 15 % compared to the basic factory vortex types GMG or GMGB installed on many boilers was shown. A project for the reconstruction of boilers TVG-8 (TVG-8M) and KVG-7.56 with an increase in convective surface area by replacing the factory pipe 28x3 mm with 32x3 mm had developed. Using the improved slot bottom burners in particular equipped with calibrated nozzles for precise dosing of natural gas into the air was envisaged. As a result of a research test of the reconstructed boilers for 3-5 years these technical solutions could increase the energy efficiency of existing TVG and KVG boilers up to the current European level —94–95 at rated heat output was shown.
